Application filed February 23, 1915. Serial No. 9,868.

To all whom it may concern:

, Be it known that I, JOHN T. RowLEY, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Apparatus for Pouring Steel and Producing Ingots, Bars, &c., of which improvement the following is a specification.

My invention relates to improvements in apparatus for pouring steel and producing ingots, bars, etc, of any desired length and cross section. 1

This application is based upon an apparatus for pouring steel, although reference may be made to my copending application, Serial No. 3840, filed January 22, 1915, in which the method of pouring steel disclosed herein. is specifically claimed. I accomplish this object by means of the apparatus hereinafter more specifically described, reference being had to the accompanying drawings, forming part hereof, in which Figure 1 represents a plan View of the apparatus. Fig. 2 is an elevation partly in section. Fig. 3 is a plan view of a modified form of the apparatus. Fig. 4 is a section on line 22 of Fig. 3. Fig. 5 is a section of the exterior metal walls which surround the refractory walls of the chambers. Fig. 6 is a detail view of one of the gates at the lower ends of the vertically disposed formers;

Referring to said drawings, and particularly Figs. 1 and 2 thereof, 1 repre nts a foundation formed of concrete or other suitable material whereon is supported the vertically disposed columns, 2, 2, whic areconnected together by cross bars, 3, and

beams, 4, on which the pouring apparatus is supported. The said pouring apparatus comprises a foundation plate, 5, of any suitable material upon'which is supported the initial pouring chamber, 6. Leading from the pouring chamber, 6, are series of con-' duits, 7, 8, which are adapted to convey metal therefrom to the chambers, 9, the metal entering the chamber, 9, through openings, 10, at an elevation somewhat below the floor of the initial chamber, 6. The metal is discharged from said chambers through series of conduits, 12, 13, into cha bers, 11, and from thence into ingot molds, or if it is desirable to form the metal into billets, etc, of any desired length and cross section, into vertically disposed formers, 14, the lower end of each of which is provided with gates or bottom plates, 16, adapted to prevent, until desired, the discharge of the I metal. When it is desired, the metal may be passed from said formers into the horizontally disposed rolls, 18, 19. The metal passes through said rolls and is preferably conveyed downward through curved chutes or guides, 20, 21, into and through a second set of rolls, 22, 23, if it is desired to further reduce the billet, and finally, is passed onto the guide platform, 24, which is adjacent to l the discharge side of said last mentioned set of rolls, respectively.

. The formers, 14, may be of any cross sectional construction, somewhat larger than the correspondingly shaped passes in the first set of rolls, and the second set of rolls may be provided with correspondingly shaped passes of less cross section than the preceding set of rolls so that the metal is subjected to reduction and solidification \from the time it passes into and through the said formers until it is finally discharged from the second set of rolls onto the guide platform. The metal vafter its passage through the second set of rolls may be out into any desirable lengths by shears (not shown) placed at the end of the guide "plat- 1 form.

In Figs. 3 and 4 I show a modification, but a preferred form of the apparatus shown in Figs. 1 and 2, the apparatus shown in Figs. 3 and 4 being particularly ap plicable to the production of ingots. In

.said figures, 25, 25, represent uprights or columns of any suitable construction, whereonare supported suitable foundation, 26, for the apparatus. The said apparatus comprises a plurality of chambers, 27, 28, 29,

preferably provided with a cover or roof, 30, I

as shown in the drawings. 31, is a fountain, the lower end of which terminates in a comparatively narrow chamber, 32, which. is connected to chamber, 27, by means of conduits, 33, 33, the ends of said conduits within said chamber, 27, having orifices, 34, through which the molten metal is forced in a vertical direction, in geyser like form, into said chamber, 27. The said chambers 27 and 28 are preferably provided with an inclined floor, 35, and the chamber, 29, with an inclined abutment X, ..The said chamopenings are stoppers, 39,

ber, 27, connects to said chamber, 28., by means of the conduits, 36, 36, and said chamber, 28, is finally connected to chamber, 29, by means of the conduits, 37, 37. The chamber, 29, is provided with a plurality of discharge openings, 38, 38, which discharge controlled by means of the 39, the said stoppers being capable of operation by the levers, 40, secured to the exterior of the chamber, 29, whereby metal may be discharged into a number of ingot molds, disposed immediately beneath said openings, one of said ingot molds, ll, being shown in Fig. i. The metal walls, 42, which inclose the refractory walls of the chambers, are provided with small perforations, 43, to permit gases to pass therethrough. It will be noted that the final chamber, 29., is larger in area than the chambers 27 and 28, and that each of the chambers is provided with an inclined bottom toward the exit thereof for the purpose of compelling the metal to pass over and drop a short distance into the various conduits connecting the different chambers. The stoppers controlling the final chambers are made of any suitable refractory substance, reinforced by a metal core or rod.

The molten metal is, in its travel from the first chamber to and through the remainin chambers agitated and turned over, permitting. the gases to escape and causing the light scoria to come to the top, with the result that ingots can be obtained which are free from blow holes and= piping and which have a greater density than the ingots resulting from the usual way of pouring metal. The escape of the gases is facilitated by causing the molten metal to alternately flow through the restricted conduits and expand in comparatively large open chambers. In Fig. 4: the metal is deflected upwardly as it enters the larger chambers, and this upward deflection of the compound, with the expansion thereof in the chamber, causes practically all of the confined gases to escape.

Having described my invention, what ll claim and desire to secure by Letters Patent is 1. An apparatus for pouringmetal and forming the same intoingots including a V comparatively large expansion plurality of restricted conduits the expansion chamber, means for causing metal to enter the expansion chamber through the plurality of restricted conduits,

ed conduits and chambers,

chamber, a leading to and means for discharging the metal from the expansion chamber.

2. An. apparatus for pouring metal and forming the same into ingots, including a comparatively large expansion chamber, a series of restricted conduits leading to the bottom of the expansion chamber, means for causing the molten metal to enter the expansion chamber throughthe restricted conduits, means for deflecting the metal upwardly as it enters the chamber, and means for discharging the metal from the expansion chamber.

8. An apparatus for pouring metal and forming the same into ingots, including a series of comparatively large open chambers, a plurality ofrestricted conduits connecting the said chambers so that the molten metal flows successively through the restrictand means for discharging the metal from the final chamber.

4. An apparatus for pouring metal and forming the same into ingots, including a series of expansion chambers arranged at successive elevations, a plurality of restricted conduits between the various expansion chambers, means for directing metal into the uppermost expansion chamber from which it through the successive series ofrestricted conduits and chambers to the lowermost chamber, and means for discharging'the metal from the uppermost chamber.

5. An apparatus for forming the same int. series of expansion cliambers arranged at successive elevations, a series of restricted conduits connecting the successive chambers, means for directing molten metal into the uppermost chamber from which it flows by gravity reflows by gravity pouring metal and ingots, including a through the various series of stricted conduits and expansion chambers into the lowermost. means for deflecting the molten metal upwardly as it enters each expansion chamber, and means for discharging the metal from the lowermost expansion chamber.

In testimony whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
